The most commonly used vibration modes can be divided into sinusoidal vibration and random vibration.Sinusoidal vibration is a test method often used in the laboratory to simulate rotation, pulsation and vibration (in shipsaircraft、vehicleThe vibration generated by, and the resonance frequency analysis of the product structure and the verification of resonance point residence are mainly divided into sweep frequency vibration and constant frequency vibration, and the severity depends on the frequency range, amplitude value, and test duration.Random vibration is used to simulate the evaluation of the shock resistance strength of the integral structure of the product and the transportation environment in the packaging state. Its severity depends on the frequency rangeGRMS、Test duration and axial direction.
The advent of the 60 ton vibrating table marks that Dongling can undertake the emergence of the vibrating table of test pieces such as the "space station" as a whole. The dynamic test of the space station will escort the operation of larger spacecraft.Dynamic test to ensure the operation of larger spacecraft.
